Are there performance cams on a Harley Road King?
Performance cams are often part of the kits, but more radical cams are certainly available. Your 2014 Road King comes equipped with slightly hotter cams than previous years, so swapping the cams should not be high on the list of priorities as far as how much bang you can expect for your buck.
Why does the Harley Davidson Road King have electronic fuel injection?
One of the pieces of technology that Harley-Davidson employed for the Road King is electronic fuel injection. This accomplishes several different things. First and foremost, it provides an avenue for the motorcycle to have more power than it would otherwise. It also allows it to operate more smoothly.
What kind of EFI system does a twin cam engine use?
The newer Delphi EFI system used on current Twin Cam engines is a Speed Density system. Speed Density EFI systems determine the engine load based on the intake manifold vacuum.
What kind of torque does a camshaft have?
Good high rpm range. Good low end torque and response in 1800-2600 rpm. Good mid range torque and response in 2400-3200 rpm range. Good mid range torque in 3000-4000 rpm range. Good mid to high rpm torque in 3800-5000 rpm range.
Which is the best range for a camshaft?
Good low end and mid range. Operating range 2000-4800 rpm. Operating range 2200-5400 rpm. Good mid range power. Operating range 3200-7500 rpm. Good high rpm range. Good low end torque and response in 1800-2600 rpm. Good mid range torque and response in 2400-3200 rpm range. Good mid range torque in 3000-4000 rpm range.
Why do you need a high range cam?
Cams help create more power (HP) in the mid to high rev ranges and come in the following types. (Its worth noting than in most applications high range Torque is unchanged but low range torque can suffer.
Performance cams are often part of the kits, but more radical cams are certainly available. Your 2014 Road King comes equipped with slightly hotter cams than previous years, so swapping the cams should not be high on the list of priorities as far as how much bang you can expect for your buck.
Why are s and S cams important for a Harley Davidson?
They were designed to improve overall performance, with a wide, flat power band that starts right off idle and keeps on pulling right up to the rev limit. You won’t have to trade low end torque for high rpm horsepower, or vice versa. The MR103 cams produce more area under the power curve for maximum overall performance improvement.
What kind of engine does a Harley Road King have?
Harley beefed up the power for the 2014 Twin Cam 103 engine used by the Road King, but modifications will increase passing power on the highway and improve your acceleration off the mark around town.
How does a longer CaM affect low rpm?
A cam with a longer intake duration will reduce static compression pressure at low speed which in turn will tend to reduce low RPM torque. But with a longer duration cam and a higher compression ratio, power at middle and high speeds will be increased which is what you wanted all along.
